I draw a line (polyline, bezier curve, circle, ...).On this drawing, I want to place on this plan a series of points, blocks, marks the space of which can be defined by:- An arithmetic (positive or negative) progression of outstrips since a certain value minimum and until a maximum value- An geometric progression of outstrips since a certain value minimum and until a maximum value- A logarithmic progress of outstrips- A progress according to a valuable list of outstrips contained, for example, in a table, a .csv file where the user can introduice thes values he needs.

For exeample :On a line selected, - I want to place crosses, a number of time but by specifying that the distance which separates 1 ° and 2 ° cross is 3 mm and the distance between the last two crosses will be 12 mm AND according to an arithmetic progression of the distances.

Another possibility would be to specify - a number of crosses to be placed, - the type of progress in the distances between crosses, - repetition or not this group of crosses (because the sum of the distances can be length of the plan), - if there is inversion in the progress in every repetition.
